Betweenthe engine and the hoisting apparatus a clutch and brakemechanism is intel-posed, This 'is'shown clearly in Fig. 11. Ahousing-.180 is keyed to the end of shaft 7(1. The outer periphery ofthis housing forms a brake-pulley against which, brakeshoes 181 arearranged to act. These brakeshoes are supported upon levers 182 whichare pivotedto the frame of the hoisting ap- 'paratus. The .other ends ofthe levers are connected by rods 183 and links 184 with a collar 185which is-loosely mounted within I a rotatabldmember 186. which isslidabl y mounted upon the engine shaft- 29; An opcrating lever 187 ispivoted to the base-plate '10 at 11 and is also connected with the collar 1S5.

levers 195. These toggle levers are connected with the rotatable member186 by.

links 19(3. The rotatable member'is arranged to form an armature for theclutch Y member 190 so that when thelatter is magnetized, it will pullthemember 186 over and, through the mechanism above described, willcause the clutch-dogs 194 to be forced out into engagement with thelionsing 180, thus locking the clutch member and the housing togetherand causing the shaft 76 of the hoisting apparatus to revolve with p theengine shaft 25). As the collar 185 does not revolve, we prefer to placeanti friction bearings 197 between it and the sides of the rotatablemember 186 which are adjacent to it. It is'evident that when therotatable member 186 has thus been shifted to actuate the brake-shoes.

and to partly close it when the'clntch is released. The lost motion(0111101311011 between the throttle valve and the centrifugal governoris provided so that this ope 'ation' \\'1ll not interfere with that ofthe governor. but- \Ve will now proceed to describe the operation of0111' invention. The car is shown at the second of the three landings.This number of landings is contacts 132 and 133 to be bridged byconlanding.

number of floors may be used. If it is desired to run the car down tothe first floor, it-

may be done by pressing either the button 140 in the car o the button143 at the first 157 designatesaconductor leadin from the side of thestoragebattery t rough the door contacts 97 98 and 99 to all of the pushbuttons. Some of these control system wires are indicated in thedrawings by rough lines so that they may be more readily traced. Pushingeither of these buttons, for example 140 or 143 will close a circuitfrom the battery 134, through conductors 157 and 158, to the winding 151of floor control magnet 150 through the latter, and back by conductor156 to the .side of the battery. The contact rod 153 which is nowconnected with the battery will be drawn down onto the contact plate58.- This will connect the side of the battery with the terminal 155 ofthe magnet, through conductor 107, magnet 122 of the reversingswitch,and conductor 108. This will cause the magnet 150 to hold its core downand will energize the right-hand side of the reversing switch so thatthe contacts which are controlled by the magnet 122 will be closed. Thiswill connect the-armature leads and 66 from the electrodynamic machinewith the and terminals of the battery, respectively, and

its shunt-field leads 67 and 68 n the same way. The terminal 69 of thespark coil 135 is connected with the main of thebattery ifall of thedoor contacts are closed, and now the contact 124 which is connectedwith the side of the battery by conductor 146,

a motor and, through its connections with the engine shaft, to start theen inc running in one'direction. The engine will now draw in a supply offuel which will be ignited in the usualmanner, so that the engine willrun under its own power. At the same time, if the door contacts areclosed, a circuit will be closed from the battery throughconductors 157,107 and 136 to the winding of magnet 130, and by conductors 137 and 156back to the battery. This magnet will cause t'act plate 131 so as tocause contact 119 to be 127 and "129, conductor 149. through theconnected with the end of the battery through conductors 157, 138 and139. The contact 118 is connected-with the other side of the battery byconductors 146, contacts magnet winding 56. Therefore, when the contacts118 and 119 are bridged by contact plate 117, the magnet 56 will beenergized to shift the spark-advancing mechanism.

:may be so adjuste The energizing coil. 191 of the clutch is connectedwith the side oflthe battery by conductors 193 and 156. Its other lead192 is connected with contact 118 so that it will be closed to the sideof the battery when contacts 132 and 133 are bridged as described, andwhen contacts 118 and 119 are connected together. Now, when the enginehas reached a predetermined rate of speed, the governor 40 will actuatethe switch armlll andcause the contact plate 117 to I be moved over toconnect the stationary contacts 118' and 119 so that the clutch' will be'thrown in to connect the hoisting apparatus mechanism and the c utchwinding will be briiken; .then the clutch will be released and' thebrake applied, and at the same time the engine will sto running.- Theseparts that 'the car will come to rest at the lower landing. Now, ifbuttons 141' or 144, or 142 or 145 are pressed similar operations tothose above described will take place, but in these cases the magnets160-01 170 will be energized and the magnet v121 will close theleft-hand side of the reversing switch. This will close the armatureleads 65 and 66 to the and leads of. the battery, and will cause theelectrodynamic machine and the engine20 to rotate in the oppositedirection. The mag' net 55 will be energized at the proper time toaccelerate the speed of the engine. If the buttons 141 or 144 have been,pressed, the car will run up until it reaches the second floor, when itwill automatically stop in It may be seen that the electrodynamicmachine acts as a starting'device for the engine, and may even assist;-the engine in driving the car if th'e'load of the latter is too heavy toallow the engine to attain its ,normal speed, but under ordinaryconditions the engine, while running at its full speed, will drive-theelectrodynamic machine fastenough to cause it to generate current backinto the battery and thus provide means for .energizin'gjhe controlsystentand for starting the engine.

This invention provides a simple electrical control system for elevatorsdriven by internal combustion engines which is auto.- matic-in itsaction and therefore requires no skilled attendant. Itnot only providesa new use for gasolcne and other steam en ginesgbut makes thepush-button or other automatic system of electrical control forelevators possible in places where a supply of electrical energy is nototherwise available.
